ALSA: hda/senary: Ensure EAPD is enabled during init

The driver sets spec->gen.own_eapd_ctl to take manual control of the
EAPD (External Amplifier). However, senary_init does not turn on the
EAPD, while senary_shutdown turns it off.

Since the generic driver skips EAPD handling when own_eapd_ctl is set,
the EAPD remains off after initialization (e.g., after resume), leaving
the codec in a non-functional state.

Explicitly call senary_auto_turn_eapd in senary_init to ensure the EAPD
is enabled and the codec is functional.
